What’s the main difference between IPv4 and IPv6? Need a simple explanation! or Can someone break dow

IPv4: “Oops, we’re out of addresses.”
IPv6: “Here’s enough for every atom on Earth.”

The difference between ipv4 and ipv6 isn’t just size—IPv6 has better autoconfig and no more ARP broadcasts. But compatibility is a pain, so dual-stack (both running) is common.
